What is it that he wants? or relationship?

I am currently dating this guy who I met through a friend who lives with him. Before we got together, we have been talking a lot and we finally kissed last weekend. Both of us had been drinking but we were fully aware of what was going on. So we were making out and he pressed himself up against me and I said that I dont do that without a commitment and asked if he wanted to try dating and he said "We'll go with the flow." Since then, we have been texting and calling each other about every other day and sometimes he would come to my place and vice versa and everytime we see each other, we always end up making out and he wants to get physical but I say no. Sometimes he will respect my wishes but other times, he gets mad at me for teasing him. Its finals week in our school so we cant really spend too much time with each other because we both need to study. I said that we need to go on an official date and he promised to take me out in the city once he gets money. Last night I went over to his place and we once again got into a makeout session and he wanted to do more. I reminded him that I dont do that without a commitment and he said that was "intense", whatever he meant by that. I asked if he was once of those guys who just wants to sleep with me and he said that he does, but thats not all he wants. Of course, not all we do is physical. We talk a lot, get to know each other more, he offers me his food, kisses me in public, tells me to come watch him play bball etc. My friend told me that he doesnt sleep around and he wants something long term, which is what I dont really understand. If he wants a relationship, why cant he ask me out already? And why is it that he always wants to get intimate? I mean is he just being a "guy"?
